Help needed : Will removing and re-adding UI-Lovelace-Minimalist break any dashboards?

I have an old error in the home-assistant.log that I really should address:

2024-04-12 16:20:26.965 WARNING (SyncWorker_5) [homeassistant.loader] We found a custom integration ui_lovelace_minimalist which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant
2024-04-12 16:20:36.752 ERROR (MainThread) [custom_components.ui_lovelace_minimalist.base] HACS Frontend repo "lovelace-auto-entities" is already installed, Remove it or disable include custom cards

I also have two dashboards called UI Lovelace Minimalist that I don’t want.

But, I do have a number of mushroom cards in my other dashboards that I need to keep.

The HACS entry Mushroom has a lovelace label, but I don’t know what that implies.

My options are one of:

  1. Do nothing
  2. Remove and reinstall UI-Lovelace-Minimalist
  3. Remove UI-Lovelace-Minimalist

To repeat: the goal is to remove two dashboards but not break other dashboards using mushroom cards
